In sololearn I have learned webtechnology languages like html, css,sql, js and php.

Question

but.. recently I have heard about some languages like Angular js, bootstrap, jQuery and xml, which are not included in sololearn.So is it necessary to learn these languages? and what is the importance of these languages?

Answer 1

sololearn has jQuery.
you need Bootstrap to have a website compatible with all devices.
and about AngularJS you can go to websites like w3school to learn it
